Abstract

The invention discloses a combined female contact element, which comprises a head part and a tail end. The head part is a cylinder body, and a step hole, an assembly hole, a nick and a flange are arranged on the head part, wherein the nick is deformed to be wedged. A cylindrical head is arranged at the tail end. The cylindrical head of the tail end penetrates through the step hole of the head part, is spliced with the assembly hole, and is in interference fit with the assembly hole. An integrated contact element is divided into a contact element head part and a contact element tail end, the contact element head part is designed and manufactured in a standard way, the contact element tail end is in interference fit with the contact element head part through a standard cylindrical head, and the nick is axially reserved in the head part, so that the elastic performance and anti-fatigue performance of the contact element head part are improved, and the aims of interface standardization of a contact element of a connector, improvement in connection reliability and remarkable reduction in coating cost are fulfilled.

Description

The negative contact of a kind of composite type

Technical field

The present invention relates to the contact of technical field of electric connectors, the negative contact of especially a kind of composite type.

Background technology

Electric connector is through the contact of contact or separates connection or the disconnection that realizes transmission signals that contact is the core component of electric connector.The connector of prior art, its head and tail end are designed to integral structure, because the termination mode of tail end and installation dimension are different; Cause the contact of electric connector different, specification is various, simultaneously; Because the disappearance of structural design, the contact of prior art cylindrical cylindrical shell has the notch of closed at both ends vertically at the periphery of cylindrical tube; Cause the elastic performance and the anti-fatigue performance of contact head undesirable, the functional reliability of connector is reduced, in addition; For prolonging the useful life of contact, need to cause the cost of coating noble metal obviously to improve to the whole coating noble metal of contact surfaces; In a word, be unfavorable for the standardized and popularized of AUI, manufacturing difficulty is big, cost is high.

Summary of the invention

The negative contact of a kind of composite type that the objective of the invention is to be directed against the deficiency of prior art and provide; The present invention is divided into contact head and contact tail end with the integral type contact; Contact head execution standardization is manufactured and designed; The contact tail end adopts the socket cap interference fit of standard to be connected with the contact head; To having gap,, have the nuclear interface standardizing of connector contact, the characteristics that connection reliability is high, the coating cost obviously reduces in head shaft to improve the elastic performance and the anti-fatigue performance of contact head.

The concrete technical scheme that realizes the object of the invention is:

The negative contact of a kind of composite type; Its characteristics comprise head and tail end, and said head is a cylindrical tube, and its cylindrical tube one end is provided with stepped hole, pilot hole successively along inwall; The other end along the barrel symmetry axis to having gap; Its gap degree of depth is 1/2～2/3 of a head total length, and this port cylindrical tube inwall is provided with flange, makes its gap distortion be wedge to the cylindrical tube application of force of this port; Tail end is a rod member, and the one of which end is that socket cap, the other end are connector; The socket cap of said tail end passes stepped hole and the pilot hole of head and pegs graft, and socket cap and pilot hole are interference fit; The stepped hole outer wall of described head is flat side.

The present invention is divided into contact head and contact tail end with the integral type contact; Contact head execution standardization is manufactured and designed; The contact tail end adopts the socket cap interference fit of standard to be connected with the contact head; In head shaft to having gap, to improve the elastic performance and the anti-fatigue performance of contact head, realize connector contact nuclear interface standardizing, improve connection reliability, obviously reduce the purpose of coating cost.

Embodiment

Consult Fig. 1, Fig. 2, Fig. 3; The present invention includes head 1 and tail end 2, said head 1 is a cylindrical tube, and its cylindrical tube one end is provided with stepped hole 10, pilot hole 11 successively along inwall; The other end along the barrel symmetry axis to having gap 14; Its gap 14 degree of depth are 1/2～2/3 of head 1 total length, and this port cylindrical tube inwall is provided with flange 13, make its gap 14 distortion be wedge to the cylindrical tube application of force of this port; Tail end 2 is a rod member, and the one of which end is that socket cap 21, the other end are connector; The socket cap 21 of said tail end 2 passes the stepped hole 10 of head 1 and pegs graft with pilot hole 11, and socket cap 21 is interference fit with pilot hole 11; Stepped hole 10 outer walls of described head 1 are flat side 12.

The present invention uses like this:

Consult Fig. 4, Fig. 5, the connection of contact head and tail end: the present invention is divided into head 1 and tail end 2 with contact, and the cylindrical tube of head 1 and pilot hole 11 are pressed standard design with the socket cap 21 of tail end 2; During use; Choose tail end 2 difform connectors to connecting object; The stepped hole 10 that only need the socket cap 21 of tail end 2 be passed head 1 is interference fit with pilot hole 11 pegs graft, and forms the contact of different connectors, the assembled of contact head 1 and tail end 2.

Consult Fig. 1, Fig. 3, the size of head 1 cylindrical tube of the present invention and the plug of connector are the standard configuration size.For improving the elastic performance and the anti-fatigue performance of contact head 1; The present invention at the cylindrical tube other end along the barrel symmetry axis to having gap 14; Its gap 14 degree of depth are 1/2～2/3 of head 1 total length; Termination distortion with gap 14 makes the integral body of gap 14 be wedge, and the design of gap 14 can improve the elastic performance and the anti-fatigue performance of contact head 1.

Consult Fig. 1; The present invention also is provided with flange 13 at port cylindrical tube inwall, and the setting of flange 13 can guarantee the connection reliability of contact head 1 and connector plug, to the local coating noble metal in flange 13 positions of head 1; The cost of coating noble metal is obviously reduced, and do not influence product quality.

Consult Fig. 2, stepped hole 10 outer walls of head 1 of the present invention are flat side 12, and the assembling or the dismounting of connector and contact is convenient in flat side's 12 setting.
